Modeling and Simulation

Featured

Researchers frequently require a quantitative understanding of the likely consequences of different actions before they can advise decisionmakers and design effective policies. RAND develops and uses statistical, econometric, and other exploratory models and simulations to analyze the potential outcomes of different policies in a range of areas such as transportation usage, health care, patient safety, and military campaigns.

Machine Learning in Public Policy
Machine learning (ML) can have a significant impact on public policy by modeling complex relationships and augmenting human decisionmaking. But overconfidence in results and incorrectly interpreted algorithms can lead to peril. With interpretability, ML can achieve its promise of more-equitable policy decisions.
